A bit of a follow up: I rolled up a potential fix for the bootstrap in the latest update. Hopefully this will fix the "Operation not supported" error.
Thanks for your response!
However, I tried various things, but nothing changed at all compared to before.
The issue where a build made on Windows 11 doesn’t run on Windows 10 is still the same. I’m building with NW.js 0.48.4.
I thought it might be dependent on my environment, so I made some fixes on my side as well, but I wasn’t able to resolve it.
As before, it seems that checking “Package game files” causes the problem.
If it’s unchecked, the build completes successfully.
The error point when building on Windows 10 is shown in the image, as you can see.
